Inductive sensor M12 metal face 68 mm connector M12 NPN NO Sn = 4 mm NF

The professional NMF12111-NF inductive sensor performs excellently in applications where what matters is detecting the actual aluminium workpiece, not individual filings or chips.

The M12 sensor belongs to solutions designed for modern industry requiring durability, precision and reliability. Ø12 x 68 mm sensors work well in standard mounting configurations that require durability and reliable detection.

Technical specification:

• Diameter: M12, high mechanical resistance of the cylindrical housing guarantees a long service life
• Length: 68 mm, used in large industrial installations requiring high reliability
• Detection range: 4 mm, repeatable signal activation distance ensures precise detection
• Detected materials: Aluminium and other non-ferrous metals (steel ignored), steel and its derivatives are not a detection target, which reduces the number of unwanted signals in aluminium processes
• Correction factor K: K = 1 for aluminium (full rated sensing range), the actual sensing range allows the model to be selected based on the actual distance to the aluminium workpiece
• Housing: Threaded, fastening with lock nuts ensures a stable installation
• Housing material: Stainless steel, suited for operation in moisture, dirt, and harsh industrial conditions
• Sensor face material: Stainless steel, increased durability of the sensor's active face under intensive use
• Mounting: Non-flush mounting, fully exposed detection zone provides maximum sensing range
• Switching function: NO, used in typical machine control applications
• Plug type: M12, the plug-in connection reduces the risk of installation errors
• Supply voltage: DC 10-30V, compatible with PLC systems and industrial automation

Applications

• Aluminium component production lines – The NF inductive sensor is used on aluminium component production lines to check the presence of parts after machining.
• Cutting, milling and turning of aluminium – Use in automating aluminium cutting, milling and turning processes increases production efficiency, even when machining chips are present around the workpiece.
• Automatic parts feeding – Use in automatic feeding of aluminium parts on production lines increases process flow.
• Assembly of building structures – The NF inductive sensor supports automation of aluminium structure assembly processes in the construction industry.
• Applications with aluminium chips – The NF inductive sensor is used in applications with aluminium chips generated during cutting, without being aimed at detecting this residue.

Benefits/Features

• Full-metal construction – the monolithic design, machined from a single piece of metal, provides high mechanical resistance and allows the solution to be used in demanding applications involving the detection of aluminium and non-ferrous metals, where the presence of filings and chips should not affect the inspection of the actual workpiece.
• Selective part detection – the solution allows inspection to be focused on the actual aluminium part, reducing the significance of individual filings and chips present around it.
• Construction for demanding applications – the full-metal design allows the solution to be used in machines where mechanical resistance and reliable detection of the actual part are important.
• K = 1 + non-ferrous metals – the K = 1 correction factor is an important parameter when designing applications that use non-ferrous materials.
• Aluminium + non-ferrous metals + K = 1 – the combination of material specialization and full rated range is an important advantage when designing applications.

When to choose this model

• For aluminium resistance welding – the part-presence sensor can check the correct position of aluminium parts before the resistance-welding process begins.
• For aluminium transport – the material-presence sensor can detect the passage of aluminium parts on a conveyor or production line.
• When resistance matters during aluminium machining – the full-metal detection element can be a suitable solution for demanding production stations.
• For demanding industrial applications – the full-metal inductive sensor will be a suitable choice when, besides aluminium detection, construction durability is important.

Connection

The sensor has an NPN output, so connect it with an M12 4-pin connection cable without LEDs. Cables with LEDs (NXOC12281…, NXOC12401…) have a yellow status LED wired for a PNP output and are not suitable for NPN sensors.
